Light on TV comes on indicating it has power and is turned on but no picture or blue screen, screen stays black.
Does the audio still work normally? If so uits most likely the inverter board which has failed and you can get a replacement inverter from www.tvcircuitboards.com
the audio works, doesn't proscan have a warrenty for things like this?

SOURCE: won't turn on
These units have a separate switching power supply that does indeed get very hot. What I have found is that a 1000mF@25v capacitor goes bad in the power supply and needs to be replaced. If your set's red power light turns green for just a second and then turns back to red without the set turning on, this may very well be your problem. You can either try to find another power supply (make sure it's rated at 12v-5amp) or take your old one to a repair shop. Be very careful if you decide to try a repair yourself, switching power supplies can pack quite a punch.
SOURCE: I have the 26 Proscan tv and the power will not
You need to take this unit in for service. You have had a failure in the power supply board and now the unit will not power-up.

SOURCE: when i turn the tv on the light turns red rather than green when lite and the screen stays blank.
There is no power coming from the step down transformer
SOURCE: green power light comes on for a split second, then red.
The power supply (AC adapter) is bad. It has enough power to light the red LED, but not enough to power the TV.http://shop.ebay.com/?_from=R40&_trksid=m38&_nkw=12+volt+5+amp+power+supply&_sacat=See-All-Categories
